node.js安装时npm WARN config global `--global`, `--local` are deprecated. Use `--location报错解决方案

背景:

今天下午 在安装node时查看npm版本号时出现这个报错,网上看了好几篇博客,解决了这个问题,在此记录一下.

解决方案

首先找到node的安装目录,然后找到需要修改的两个配置文件 npm.cmd 和 npm .

然后打开这两个配置文件,找到以下代码 prefix -g 将其替换为 prefix --location=global
下面为替换后的两个代码:
npm:

 

#!/usr/bin/env bash
(set -o igncr) 2>/dev/null && set -o igncr; # cygwin encoding fix

basedir=`dirname "$0"`

case `uname` in
  *CYGWIN*) basedir=`cygpath -w "$basedir"`;;
esac

NODE_EXE="$basedir/node.exe"
if ! [ -x "$NODE_EXE" ]; then
  NODE_EXE="$basedir/node"
fi
if ! [ -x "$NODE_EXE" ]; then
  NODE_EXE=node
fi

# this path is passed to node.exe, so it needs to match whatever
# kind of paths Node.js thinks it's using, typically win32 paths.
CLI_BASEDIR="$("$NODE_EXE" -p 'require("path").dirname(process.execPath)')"
NPM_CLI_JS="$CLI_BASEDIR/node_modules/npm/bin/npm-cli.js"

NPM_PREFIX=`"$NODE_EXE" "$NPM_CLI_JS" prefix --location=global`
if [ $? -ne 0 ]; then
  # if this didn't work, then everything else below will fail
  echo "Could not determine Node.js install directory" >&2
  exit 1
fi
NPM_PREFIX_NPM_CLI_JS="$NPM_PREFIX/node_modules/npm/bin/npm-cli.js"

# a path that will fail -f test on any posix bash
NPM_WSL_PATH="/.."

# WSL can run Windows binaries, so we have to give it the win32 path
# however, WSL bash tests against posix paths, so we need to construct that
# to know if npm is installed globally.
if [ `uname` = 'Linux' ] && type wslpath &>/dev/null ; then
  NPM_WSL_PATH=`wslpath "$NPM_PREFIX_NPM_CLI_JS"`
fi
if [ -f "$NPM_PREFIX_NPM_CLI_JS" ] || [ -f "$NPM_WSL_PATH" ]; then
  NPM_CLI_JS="$NPM_PREFIX_NPM_CLI_JS"
fi

"$NODE_EXE" "$NPM_CLI_JS" "$@"

复制代码

npm.cmd:

:: Created by npm, please don't edit manually.
@ECHO OFF

SETLOCAL

SET "NODE_EXE=%~dp0\node.exe"
IF NOT EXIST "%NODE_EXE%" (
  SET "NODE_EXE=node"
)

SET "NPM_CLI_JS=%~dp0\node_modules\npm\bin\npm-cli.js"
FOR /F "delims=" %%F IN ('CALL "%NODE_EXE%" "%NPM_CLI_JS%" prefix --location=global ') DO (
  SET "NPM_PREFIX_NPM_CLI_JS=%%F\node_modules\npm\bin\npm-cli.js"
)
IF EXIST "%NPM_PREFIX_NPM_CLI_JS%" (
  SET "NPM_CLI_JS=%NPM_PREFIX_NPM_CLI_JS%"
)

"%NODE_EXE%" "%NPM_CLI_JS%" %*

复制代码

第一次打开会遇到提示非管理员权限无法修改的警告,只需在文件属性里修改权限,增加修改权限,然后重新打开并修改代码即可.

当这两个配置文件都修改完毕后,重新打开cmd提示命令行,重新检测版本号就会发现不会再提示报错信息.
如下图所示:
